Answer:
The function in Python3 is as follows
def Distance(x1, y1, x2, y2):
dist = ((x1 - x2)**2 +(y1 - y2)**2)**0.5
return dist
Explanation:
This defines the function
def Distance(x1, y1, x2, y2):
This calculates distance
dist = ((x1 - x2)**2 +(y1 - y2)**2)**0.5
This returns the calculated distance to the main method
return dist

Write a recursive method named hanoi that prints a solution to the classic Towers of Hanoi puzzle. Your method should accept three integer parameters representing the number of disks, the starting page number, and ending peg number. Your method should print the solution to the game to move from the given start peg to the given end peg. For example, the call of hanoi(3, 1, 3); should print the following output to move the three pegs from peg
Answer:
Explanation:
The following recursive method is written in Java. It creates a simulation of the towers of Hanoi and outputs every step-by-step instruction on how to solve it. The output for the code can be seen in the attached picture below.
class Brainly {
public static String hanoi(int numOfDisks, int startPeg, int endPeg) {
int helpPeg;
String sol1, sol2, MyStep, mysol; // Contains moves
if (numOfDisks == 1) {
return "Move from " + startPeg + " to " + endPeg + "\n";
} else {
helpPeg = 6 - startPeg - endPeg; // Because startPeg + helpPeg + endPeg = 6
sol1 = hanoi(numOfDisks - 1, startPeg, helpPeg);
MyStep = "Move from " + startPeg + " to " + endPeg + "\n";
sol2 = hanoi(numOfDisks - 1, helpPeg, endPeg);
mysol = sol1 + MyStep + sol2; // + = String concatenation !
return mysol;
}
}
public static void main(String[] args) {
String output = hanoi(3, 1, 3);
System.out.println(output);
}
}
In numerical methods, one source of error occurs when we use an approximation for a mathematical expression that would otherwise be too costly to compute in terms of run-time or memory resources. One routine example is the approximation of infinite series by a finite series that mostly captures the important behavior of the infinite series.
In this problem you will implement an approximation to the exp(x) as represented by the following infinite series,
exp(x) = Infinity n= 0 xn/xn!
Your approximation will be a truncated finite series with N + 1 terms,
exp(x, N) = Infinityn n = 0 xn/xn!
For the first part of this problem, you are given a random real number x and will investigate how well a finite series expansion for exp(x) approximates the infinite series.
Compute exp(x) using a finite series approximation with N E [0, 9] N (i.e. is an integer).
Save the 10 floating point values from your approximation in a numpy array named exp_approx. exp_approx should be of shape (10,) and should be ordered with increasing N (i.e. the first entry of exp_approx should correspond to exp(x, N) when N = 0 and the last entry when N = 9).
Answer:
The function in Python is as follows:
import math
import numpy as np
def exp(x):
mylist = []
for n in range(10):
num = (x**n)/(math.factorial(n))
mylist.append([num])
exp_approx = np.asarray(mylist)
sum = 0
for num in exp_approx:
sum+=num
return sum
Explanation:
The imports the python math module
import math
The imports the python numpy module
import numpy as np
The function begins here
def exp(x):
This creates an empty list
mylist = []
This iterates from 0 to 9
for n in range(10):
This calculates each term of the series
num = (x**n)/(math.factorial(n))
This appends the term to list, mylist
mylist.append([num])
This appends all elements of mylist to numpy array, exp_approx
exp_approx = np.asarray(mylist)
This initializes the sum of the series to 0
sum = 0
This iterates through exp_approx
for num in exp_approx:
This adds all terms of the series
sum+=num
This returns the calculated sum
return sum

In a spreadsheet what does the following symbol mean?
$
Answer:
$ = dollar sign
Explanation:
In a spreadsheet, the $ symbol is the symbol of the dollar. The dollar is the currency of the United States.
What is currency?Currency is a form of payment for goods and services. In a nutshell, it is money in the form of paper and coins that is usually issued by a government and is generally accepted as a form of payment at face value.
Currency exchange rates differ between businesses because each one distorts the interbank rate to maximize profits. We encounter numerous competitors who post interbank rates internet as bait to attract new customers, but once the customers are onboard, they drastically change the rate, typically not in the customers' favor.
Therefore, the $ symbol represents the dollar in a spreadsheet. The US dollar is the country's currency.

Requirements description:
Assume you work part-time at a Cafe. As the only employee who knows java programming, you help to write an ordering application for the store.
The following is a brief requirement description with some sample output.
1. Selecting Breakfast or Lunch(5 points)
When the program starts, it first shows option Breakfast or Lunch. A sample output is as follows.
=== Select Breakfast or Lunch: ===
1. Breakfast
2. Lunch
You are supposed to validate the input.
If the user enters a letter or a number not between 1 and 2, the user will see an error message.
A sample output for invalid number is as follows.
Select Breakfast or Lunch [1, 2]: 0
Error! Number must be greater than 0.
Select Breakfast or Lunch [1, 2]:
2. Selecting Coffee (20 points)
When the program continues, it shows a list/menu of coffee and their prices, then asks a user to select a coffee by entering an integer number. A sample output is as follows.
=== Select Coffee: ===
1 Espresso $3.50
2 Latte $3.50
3 Cappuccino $5.00
4 Cold Brew $3.00
5 Quit Coffee selection
Select a coffee [1, 5]:
You are supposed to validate the input.
If the user enters a letter or a number not between 1 and 5, the user will see an error message.
A sample output for invalid number is as follows.
Select a coffee [1, 5]: 0
Error! Number must be greater than 0.
Select a coffee [1, 5]:
In your program, you can hard-code the information for coffee (i.e., coffee names and prices) shown above, such as "1 Espresso $3.50" and use the hard-code price, such as 3.50, for calculation of a total price of the order.
After the user makes a choice for coffe, such as 2 for Latte. The program continues asking for selecting a coffee so that the user can have multiple coffee orders. The user can enter "5" to quit coffee selection. A sample output is as follows.
=== Select Coffee: ===
1 Espresso $3.50
2 Latte $3.50
3 Cappuccino $5.00
4 Cold Brew $3.00
5 Quit Coffee selection
Select Coffee: [1, 5]: 2
=== Select Coffee: ===
1 Espresso $3.50
2 Latte $3.50
3 Cappuccino $5.00
4 Cold Brew $3.00
5 Quit Coffee selection
Select Coffee: [1, 5]: 5
3. Selecting Food (10 points)
After Coffee selection, the program shows food selection. A sample output is as follows.
=== Select Food: ===
1 Tuna Sandwich $10.00
2 Chicken Sandwich $10.00
3 Burrito $12.00
4 Yogurt Bowl $8.00
5 Avocado Toast $8.00
6 Quit Food selection
Select Food: [1, 6]: 1
Input validation is needed and works as before. Like Coffee selection which allows selecting multiple Coffee orders, food selection also repeats after the user enters a valid number between 1 and 5.
You hard-code the information for food shown above, such as "1 Tuna Sandwich $10.00" and use the hard-code price, such as 10.00, for calculation of the total price of the order.
Answer:

Suppose that a minus sign in the input indicates pop the stack and write the return value to standard output, and any other string indicates push the string onto the stack. Further suppose that following input is processed:
this parrot - wouldn't voom - if i put -- four thousand --- volts - through it -
What are the contents (top to bottom) left on the stack?
a. through wouldn't this.
b. this wouldn't through.
c. it through wouldn't.
d. it through volta.
e. volts through it.
Answer:
e. volts through it
Explanation:
volts through it
The contents (top to bottom) left on the stack is volts through it. Thus, option E is correct.
What is standard output?When a computer program begins execution, standard streams are interconnected input and output channels of communication between the program and its surroundings. The three I/O connections are known as standard input (stdin), standard output (stdout), and standard error (stderr).
A negative sign in the input indicates that the stack should be popped, and the return value should be sent to standard output, whereas any other string means that the string should be pushed into the stack. Assume that the following input is processed: this parrot would not voom if I pushed — four thousand —- volts - through it.
The contents of the stack (from top to bottom) are volts via it. As a result, option E is correct.

The given SQL creates a Movie table and inserts some movies. The SELECT statement selects all movies released before January 1, 2000 Modify the SELECT statement to select the title and release date of PG-13 movies that are released after February 1, 2008. Run your solution and verify the result table shows just the titles and release dates for The Dark Knight and Crazy Rich Asians. 3 6 1 CREATE TABLE Movie ( 2 ID INT AUTO_INCREMENT, Title VARCHAR(100), 4 Rating CHAR(5) CHECK (Rating IN ('G', 'PG', 'PG-13', 'R')), 5 ReleaseDate DATE, PRIMARY KEY (ID) 7); 8 9 INSERT INTO Movie (Title, Rating, ReleaseDate) VALUES 19 ('Casablanca', 'PG', '1943-01-23'), 11 ("Bridget Jones's Diary', 'PG-13', '2001-04-13'), 12 ('The Dark Knight', 'PG-13', '2008-07-18'), 13 ("Hidden Figures', 'PG', '2017-01-06'), 14 ('Toy Story', 'G', '1995-11-22'), 15 ("Rocky', 'PG', '1976-11-21'), 16 ('Crazy Rich Asians', 'PG-13', '2018-08-15'); 17 18 -- Modify the SELECT statement: 19 SELECT * 20 FROM Movie 21 WHERE ReleaseDate < '2000-01-01'; 22
Answer:
The modified SQL code is as follows:
SELECT Title, ReleaseDate FROM movie WHERE Rating = "PG-13" and ReleaseDate > '2008-02-01'
Explanation:
The syntax of an SQL select statement is:
SELECT c1, c2, c...n FROM table WHERE condition-1, AND/OR condition-n
In this query, we are to select only the title and the release date.
So, we have:
SELECT Title, ReleaseDate
The table name is Movie.
So, we have:
SELECT Title, ReleaseDate FROM movie
And the condition for selection is that:
Ratings must be PG-13
And the date must be later than February 1, 2008
This implies that:
Rating = "PG-13"
ReleaseDate > '2008-02-01'
So, the complete query is:
SELECT Title, ReleaseDate FROM movie WHERE Rating = "PG-13" and ReleaseDate > '2008-02-01'
Rideshare companies like Uber or Lyft track the x,y coordinates of drivers and customers on a map. If a customer requests a ride, the company's app estimates the minutes until the nearest driver can arrive. Write a method that, given the x and y coordinates of a customer and the three nearest drivers, returns the estimated pickup time. Assume drivers can only drive in the x or y directions (not diagonal), and each mile takes 3.5 minutes to drive. All values are doubles; the coordinates of the user and of the drivers are stored as arrays of length 2. 289222.1780078.qx3zqy7
Answer:
The program in Java is as follows:
import java.util.*;
public class Main{
public static void main (String[]args){
Scanner input = new Scanner(System.in);
double user[] = new double[2]; double dr1[] = new double[2];
double dr2[] = new double[2]; double dr3[] = new double[2];
System.out.print("Enter user coordinates: ");
for(int i =0;i<2;i++){ user[i] = input.nextDouble(); }
System.out.print("Enter driver 1 coordinates: ");
for(int i =0;i<2;i++){ dr1[i] = input.nextDouble(); }
System.out.print("Enter driver 2 coordinates: ");
for(int i =0;i<2;i++){ dr2[i] = input.nextDouble(); }
System.out.print("Enter driver 3 coordinates: ");
for(int i =0;i<2;i++){ dr3[i] = input.nextDouble(); }
double dr1dist = Math.abs(user[0] - dr1[0]) + Math.abs(user[1] - dr1[1]);
double dr2dist = Math.abs(user[0] - dr2[0]) + Math.abs(user[1] - dr2[1]);
double dr3dist = Math.abs(user[0] - dr3[0]) + Math.abs(user[1] - dr3[1]);
System.out.println("Estimated pickup time of driver 1 "+(3.5 * dr1dist)+" minutes");
System.out.println("Estimated pickup time of driver 2 "+(3.5 * dr2dist)+" minutes");
System.out.println("Estimated pickup time of driver 3 "+(3.5 * dr3dist)+" minutes");
}
}
Explanation:
The following array declarations are for the customer and the three drivers
double user[] = new double[2]; double dr1[] = new double[2];
double dr2[] = new double[2]; double dr3[] = new double[2];
This prompts the user for the customer's coordinates
System.out.print("Enter user coordinates: ");
This gets the customer's coordinate
for(int i =0;i<2;i++){ user[i] = input.nextDouble(); }
This prompts the user for the driver 1 coordinates
System.out.print("Enter driver 1 coordinates: ");
This gets the driver 1's coordinate
for(int i =0;i<2;i++){ dr1[i] = input.nextDouble(); }
This prompts the user for the driver 2 coordinates
System.out.print("Enter driver 2 coordinates: ");
This gets the driver 2's coordinate
for(int i =0;i<2;i++){ dr2[i] = input.nextDouble(); }
This prompts the user for the driver 3 coordinates
System.out.print("Enter driver 3 coordinates: ");
This gets the driver 3's coordinate
for(int i =0;i<2;i++){ dr3[i] = input.nextDouble(); }
This calculates the distance between driver 1 and the customer
double dr1dist = Math.abs(user[0] - dr1[0]) + Math.abs(user[1] - dr1[1]);
This calculates the distance between driver 2 and the customer
double dr2dist = Math.abs(user[0] - dr2[0]) + Math.abs(user[1] - dr2[1]);
This calculates the distance between driver 3 and the customer
double dr3dist = Math.abs(user[0] - dr3[0]) + Math.abs(user[1] - dr3[1]);
The following print statements print the estimated pickup time of each driver
System.out.println("Estimated pickup time of driver 1 "+(3.5 * dr1dist)+" minutes");
System.out.println("Estimated pickup time of driver 2 "+(3.5 * dr2dist)+" minutes");
System.out.println("Estimated pickup time of driver 3 "+(3.5 * dr3dist)+" minutes");

Counting the character occurrences in a file
For this task you are asked to write a program that will open a file called “story.txt
and count the number of occurrences of each letter from the alphabet in this file.
At the end your program will output the following report:
Number of occurrences for the alphabets:
a was used-times.
b was used - times.
c was used - times .... ...and so, on
Assume the file contains only lower-case letters and for simplicity just a single
paragraph. Your program should keep a counter associated with each letter of the
alphabet (26 counters) [Hint: Use array|
| Your program should also print a histogram of characters count by adding
a new function print Histogram (int counters []). This function receives the
counters from the previous task and instead of printing the number of times each
character was used, prints a histogram of the counters. An example histogram for
three letters is shown below) [Hint: Use the extended asci character 254]:

int row,i;
for (i = 0; i < 26; i++) {
if (counters[i] > largest) {
largest = counters[i];

The speed density fuel injection system uses the blank sensor as the primary sensor as the primary sensor to determine base pulse width
A. Map
B TP
C Maf
D baro
Answer:
A) Map
Explanation:
All gasoline (petrol) fuel systems need ways or method that will be calculating amount of the air that is entering the engine.This is true as regards mechanical fuel injection, carburetors and electronic fuel injection.Speed density system fall under one of this method. "Speed" in this context means the speed of the engine while "density" means density of the air. The Speed is been measured using the distributor, crankshaft position sensor could be used here. The Density emerge from from measuring of the air pressure which is inside the induction system, using a typical "manifold absolute pressure" (MAP) sensor as well as air temperature sensor. Using pieces of information above, we can calculate
mass flow rate of air entering the engine as well as the correct amount of fuel can be supplied. With this system,
the mass of air can be calculated. One of the drawback if this system is that
Any modification will result to incorrect calculations. Speed-Density can be regarded as method use in estimation of airflow into an engine so that appropriate amount of fuel can be supplied as well as. adequate spark timing. The logic behind Speed-Density is to give prediction of the amount of air ingested by an engine accurately during the induction stroke. Then this information could now be used in calculating how much fuel is required to be provided, This information as well can be used in determining appropriate amount of ignition advance. It should be noted The speed density fuel injection system uses the Map sensor as the primary sensor to determine base pulse width

B) Worms are impossible to remove; viruses can be tracked and removed.
C) Worms are stronger than viruses; viruses are stronger than spam.
D) Worms travel independently of human action; viruses require human actions.
Answer:
Option C
Explanation:
Option A is incorrect as Worm is a form of malware
Option B is incorrect because antivirus can remove all forms of malware
Option C is correct because a worm is more problematic as compared to the virus. Also, viruses are weaker than worm because they need a host file to run but a worm can work independently.
Option D is also incorrect because both are able to self replicate.
Can you debug the following code using the given test code?public class SavingAccount{ // interest rate for all accounts private static double annualInterestRate = 0; private final double savingsBalance; // balance for currrent account // constructor, creates a new account with the specified balance public void SavingAccount( double savingsBalance ) { savingsBalance = savingsBalance; } // end constructor // get monthly interest public void calculateMonthlyInterest() { savingsBalance += savingsBalance * ( annualInterestRate / 12.0 ); } // end method calculateMonthlyInterest // modify interest rate public static void modifyInterestRate( double newRate ) { annualInterestRate = ( newRate >= 0 && newRate <= 1.0 ) ? newRate : 0.04; } // end method modifyInterestRate // get string representation of SavingAccount public String toString() { return String.format( "$%.2f", savingsBalance ); } // end method toSavingAccountString} // end class SavingAccount Using this test codepublic class SavingAccountTest{ public static void main(String[] args) { SavingAccount s1 = new SavingAccount(400); SavingAccount s2 = new SavingAccount(1000); SavingAccount.modifyInterestRate(0.05); System.out.printf("SavingAccount 1 is: %s\nSavingAccount 2 is: %s\n", s1, s2); s1.calculateMonthlyInterest(); s2.calculateMonthlyInterest(); System.out.printf("\nSavingAccount 1 after the interest is: %s\nSavingAccount 2 after the interest is: %s\n", s1, s2); SavingAccount.modifyInterestRate(.025); s1.calculateMonthlyInterest(); s2.calculateMonthlyInterest(); System.out.printf("\nSavingAccount 1 after the new interest is: %s\nSavingAccount 2 after the new interest is: %s\n", s1, s2); }}
Answer:
Explanation:
The reason the code was not working was due to a couple of errors. First, the SavingAccount class needed to be public so that it can be accessed within the same file. Secondly, the savingsBalance variable was set to final and therefore could not be modified, the final keyword needed to be removed. Lastly, the constructor for the SavingAccount class was incorrect. Constructors do not use the keyword void and instance class variables need to be referenced using the this keyword.
class SavingAccount{
// interest rate for all accounts
private static double annualInterestRate = 0;
private double savingsBalance;
public SavingAccount(double savingsBalance) {
this.savingsBalance = savingsBalance;
}
public void calculateMonthlyInterest() {
savingsBalance += savingsBalance * ( annualInterestRate / 12.0 );
}// end method calculateMonthlyInterest
// modify interest rate
public static void modifyInterestRate( double newRate ) {
annualInterestRate = ( newRate >= 0 && newRate <= 1.0 ) ? newRate : 0.04;
} // end method modifyInterestRate
// get string representation of SavingAccount
public String toString() { return String.format( "$%.2f", savingsBalance );
} // end method toSavingAccountString
}// end class SavingAccount
// Using this test codepublic
//
class SavingAccountTest{
public static void main(String[] args) {
SavingAccount s1 = new SavingAccount(400);
SavingAccount s2 = new SavingAccount(1000);
SavingAccount.modifyInterestRate(0.05);

The project downloaded contains a package (folder) named Q1 within the src folder. Inside Q1 is a Java class named Questions. The purpose of Question 1 is to examine your understanding of loops and branching conditions. You should implement all of your code for this question in the main method of the Questioni class. While significant detail is provided below to be sure you undertand what is required, please note that the amount of code required to solve this question (Parts a-c) is less than 10 lines (total). In the Question1 class, you are given a line of code that generates a random number between 0 and 1. Math.random(): //generates number between 0 and 1 val
You are to create a loop which, in each iteration, generates a new random value, assigns it to val using the line provided and checks to see if that val is greater than 0.5. If val is greater than 0.5, a variable named counter should be incremented. The loop should continue this process (generate random value, check if it is greater than 0.5) until a total of three random numbers generated are greater than 0.5 (values do not have to be consecutive). You should also use the variable named numIterations, which is included for you, to track how many iterations of your loop were required for you to generate three random numbers greater than 0.5. A printin() statement is included for you that displays the value of numlterations. As an example of how the program should behave, if the following sequence of random numbers are randomly generated from your loop
0.3, 0.7,0.2, 0.6,0.9
then numIterations would equal 5 (the third value greater than 0.5 occured on the fifth iteration).
If
0.6, 0.8, 0.75
was the random sequence of numbers generated by your loop, then numlterations would equal 3 (the third value greater than 0.5 occured on the third iteration).
These are two examples to illustrate the scenario given in Question 1. Since at each iteration of your loop the number generated is random, the value of numIterations that your program observes may be any value greater than or equal to 3. Note that your program does not need to print out each of the random values that it generates. The steps to solve Question 2 are broken down as follows.
a. Implement a branching condition that increases the variable counter by 1 if val is larger than 0.5 1
b. Add a loop around the code created in Part a that continues until counter equals 3.
c. Use the variable numlterations to count how many times your loop iterates.

Explanation:
1) Create a class called Villain. Specifically, a Villain has the following fields: .name (String)
a number of evil plans (int) In addition, a Villain has the following methods: • a constructor that accepts an argument for each of the fields . a copy constructor
an equals method, which checks/returns whether all the fields are the same
a toString method
2) Create a class called Crazy Villain, which inherits from Villain. Specifically, a Crazy Villain has the following additional fields:
a crazy laughter (String)
a crazy idea (String In addition, write code for the following Crazy Villain methods:
a constructor that accepts an argument for each of the fields
a toString method that overrides the Villain toString method, in order to include the additional fields You do not need to instantiate/demo Villain or Crazy Villain objects.
Answer:
Explanation:
The following code is written in Java and creates both of the classes as requested with their variables and methods as needed. The crazyVillain class extends the Villain class and implements and overrides the needed variables and methods. Due to technical reasons, I have added the code as a txt file below.
A "Pythagorean Triple" is a set of integers which will make the sides of a right triangle when used in the calculation of Pythagoras’ Theorem. For example, "3, 4, 5" is a Pythagorean Triple. Write a short "C" function that takes three decimal integers and determines if they are a "Pythagorean Triple". The function should return a boolean which is true if the three numbers fit the pattern, and false otherwise. DO NOT write a "main()" method in this code! [15 pts.]
Answer:
The function in C is as follows:
bool checkPythagoras(int a, int b, int c ){
bool chk = false;
if(a*a == b*b + c*c || b*b == a*a + c*c || c*c == b*b + a*a){
chk = true;
}
return chk;
}
Explanation:
This defines the function. It receives three integer parameters a, b and c
bool checkPythagoras(int a, int b, int c ){
This initializes the return value to false
bool chk = false;
This checks if the three integers are Pythagorean Triple
if(a*a == b*b + c*c || b*b == a*a + c*c || c*c == b*b + a*a){
If yes, the return value is updated to true
chk = true;
}
This returns true or false
return chk;
}
